To all whom t mag/concern.'

Be it known that we, ALBERT DE LAsKI, PETER D. THROPP, and HENRY DECK, citizens of the United States,and residents of Trenton, in the county of Mercer and Stateof 'New Jersey, have invented a new and useful Vehicle-Tire, of which the following is a specification.

Our invention relates to a vehicle-tire, and more particularly to a tire of what is known as the .clencher-tire, withfthe object in View of making the clencher-tube itself an inflatable pneumatic tube regardless of whether'it does `or does not have an inner iniatable tube.

A -practical embodiment/of our inventiony is represented in the accompanying drawings, in which- Figure 1 is a transverse section of a tire and rim'em bodying our invention and showing the parts in assembled adjustment, and Figs. 2, 3, 4, and 'represent similar views of modified forms. y

No inner inflatable tube is shown in connection with the present illustration of our inven.

tion, as such a tube formsl no part thereof, although itmight be used in connection with it, if desired. v'

The clencher-tube is denoted by 1 and is, as usual, separated at its base throughoutA its length and held in position by iianged keepers (denoted in Figs. 1 and 2 by 2 and 3) and having depending annular anges 4 and 5, through which the keepers are bolted to the rim 6 by through-bolts 7.

In theform shown in Figs. 1 andl 2 the keepers are curved inwardly at their outer edges to retain the base of the tube 1 against displacement in a radial direction, as well as in'a lateral direction, and .these keepers are further provided at the outer face of the rim 6 with inwardly-projecting flanges 8 and 9,

which extend over the outer face of the rim 6 into proximity7 to one another and serve as The opposite faces of the 4base-sections 10 and 11 of the tube 1 are, as shown in Fig. 1, inclined, so as to gradually approach each other as they eX- tend downwardly toward their seats 8 and 9, and also are provided with recesses 12 and 13. These inclined faces of the base portions. 10 and 11 are covered with layers of soft rubber 14, which is so formed as to ll the recesses 12 and 13. This soft--rubber body is forced tightly against the opposite inclined faces of the base portions 10 and 11 by means of an when it is iniated by means of an anti-elongating ring 16, preferably of thin metal and sufficiently wide to cover. the base of the Wedge-.piece 15, the upper edges ofthe softrubber layer onV opposite sides of the wedgepiece lapping a greater or lesser distance over onkto the baseportions 10 and 11 of the clenchertu e.

5 .The above structureforrnsan effective seal at the base of the clencher-tube, so that it may be infiated in the samev manner in which the ordinary inflatable tube is inflated by means of a valve of` ordinary structure applied thereto. When itis so inflated, the pressure of the air within it will tend to hold the Wedge" 15 snugly in position regardless of the-eect of the ring 16, and so hold the tube tightly sealed against` escape of air from Within. This structure has the advantage which is peculiar to clencher-tires, in that it may be opened at pleasure for repairs, while it has the additional advantage of forming in itselfk an inflatable tube and so becomes a pneumatic tire. The structure is simple and is not liable to get out of order.

In the form shown in Fig. 2 the base por- 'tions vof the clencher-tire have their adjacent faces inclined at a greater angle to the radial planev and are made plain instead of grooved.

In other respects the structure is quite simi- Y lar to that shown in Fig. 1. These modified. base portions, as shown in Fig. 2, are denoted by 17 and 18.

In the form shown in Fig. 3 the keepers (denoted by 19 and 20) are shown without the inwardly-projecting flanges 8 and 9, a tire 21 being shown surrounding the. outer face 'of the rim 6 and forming a seat for the base por-l` tube resting directly on the outer face of the A rim. In this instance the anti-elongating strips consist of Wires 25 26, embedded in the base portions 23 24, respectively, and the opposite faces of these base portions of the clenchertube are provided with V-shaped recesses 27 23 for receiving the opposite sides of a soft-rubber ring 29, rectangular in cross-section and set With its edges at the bottoms of the V-shaped recesses.

In the form shown in Fig. 5 the keepers (denoted by 30 31) do not turn inwardly at their outer edges to hold the tire ag'ainst the radial displacement, but extend in radial planes up the outer sides of the base portions of the clencher-tube. In this forrn the rim 6 is provided With a tire similar to the form shown in Fig. 3, While the base portions 32 33 of the clencher-tube have their bases notched to extend down past the edges of the tire 21 and their adjacent faces provided with recesses similar to those shown in Fig. l, the faces being substantially parallel instead of inclined, as in Fig. l, and spaced apart to receive between them a ring 34, of soft rubber, having on its opposite sides projections to fit the recesses in the faces of the basev portions 32 33. In this form lthe clencher-tube is held in position on the rim by means ofv tvvo anti-elongating strips 35 36, located on opposite sides of the soft-rubber ring 34.

'Ihese several illustrations represent types of numerous specific forms which the softrubber sealing material may assume in its relation to the base portions of the clenchertube and of the various forms which the base portions themselves and their keepers may assume with respect to the rim of the Wheel.

That We claim isl. The combination with a clencher-tirc having the opposite faces of its base portion inclined and a soft-rubber ring applied to said inclined surfaces of a wedge-shaped annular ring of harder rubber engaged with the softrubber annular ring for holding thc latter in snug contact with the inclined faces of the base portion of the tire and means for holding the tire in position.

2. The combination with a clencher-tire having the opposite faces of its base portion rccessed, of asoft-rubber ring arranged to engage the recesses in the opposite faces of said base portions and'means for holding the softrubber ring in position.

3. The combination with a clencher-tire having the opposite faces of its base portion inclined and provided with recesses, of a softrubber ring arranged to engage the said inclined faces and recesses and means for holding the soft-rubber ring in position to seal the tire.

In testimony that we claim the fo1e;:going` as our invention we have signed our naines, in presence of two witnesses, this 14th day of November, 1903.
